Let’s assume we got a database for todolist and want to query all item that are important and are not already done. In SQL, I will use something like

SELECT * FROM todolist WHERE important = true AND state <> 'done'

How can we perform that type of request in an indexeddb nosql database?
With indexes?
Another way?
Not possible?

As I know to filter result on important = true :

objectstore.index('important').openCursor(IDBKeyRange.only('true'))

But I do not know how to filter on state <> 'done' as we got only IDBKeyRange.only(z).

And I do not know how to filter on both clause.

N.B. : In MongoDB we do :

db.userdetails.find({"date_of_join" : "16/10/2010","education":"M.C.A."})

You will need indexes for that, and you can retrieve the data using a cursor where you can provide one filter.
